` T o all whom it may concern:

Be it' known that I, ALBERT LUOHINGER, a

'citizenpf Switzerland, residing at the city of New York, borough of Bronx, eonn'ty and State of New York, have invented a new and Improved Motor-Sleigh, of which the following is aspecifieation.

This invention relatesA to an improved motor sleigh, which is propelled by means of 'a pair of driving wheels' arranged between a side view partlyin section of my improved gaged by a pinion .16 fast on a spindle 17 of the steeringr -wheel 18. By the means describedl the forward runners 11 may be tnrned in eitherV direction to' steer the vehicle.

Between the rear runners 12 are arranged apair of propelling wheels 19 each provided with snow creepers 20. Wheels 19 are mounledon a laterallytilting and vertically movable axle 21 journaled in the lower ends of a pair ot vertically movableI rods 22. their upper ends through a perforated cross piece 23 of the sleigh in which they Iind a bearing. Rods 22 also pass through opposite ends of a leaf spring 24 connectedat its'center to a rack 25 guided in cross piece 23. This rack'is en Specification of Letters Patent. 1 Application filed August 101907. Serial No. 387.963

' gaged by a pinion motor sleigh, Fig. 2 a bottom view, and Fig.

Patented Dec. 10. 1907.

26 fast on a rock shaft 27 that may be turned by treadle 29 through arm 28. The ends of spring 24 bear on collars 30 fast on rods 22, while between sprin 24, and cross piece 23, rods 22 are encircle by auxiliary coiled springs 31.

In order to'hold axle 21 against rearward displacement While the sleigh is in rnotion, it is hung in the rear ends of a pair of braces 32, the forwardends of whieh'are pivoted to the sleigh at 33. 4The perforations in cross-piece 23 that accommodate rods 22, are of a size sui'cient to'fpermit the laterally tilting motion of axle 21, as well as its movement around center 33. Axle- 21 is rotated from a suitable lnotor (not shown) by chain 34 and@ chain wheel 35. y

In use, rotation of axle 21 will cause the propeller wheels 19 to gras the snow with their creepers 20, so as to raw theyehiele forward. on onel side of the road than on the et er, axle 21 will tilt, (Fig. 3) so as to partly Withdraw the buried wheel. The driver by means of treadle 29 can depress axle 21, to sink wheels 19 into the snow-to anydepth`de` In case the snow is banked hi her sired, and thus adjust the propellers to diierent grades and to different consistency of the snow.
